You may get into troubles if you installed recently Java version 8u141. It had a bug that prevent running our java application through Java Web Start. A new release ( 8u144 ) has been deployed from https://www.java.com.

The JMMC Stellar Diameter Catalog (JSDC) version 2

This catalogue contains stellar angular diameter estimates for nearly
all the stars of the Hipparcos and Tycho catalogue that have an
associated spectral type in Simbad. The median error on the
diameters is around 1.5%, with possible biases of around ∼2%. For each
object, the limb-darkened diameter retained is the mean value of
several estimates performed using different couples of photometries.
The chi-square representing the dispersion between these values is
also given (it is below 2 for ∼400000 stars). An additional flag
signals stars that could represent a risk if chosen as calibrators for
Optical Long-Baseline Interferometry, independently of the correctness
of their apparent diameter estimate.

You may prefer to use our specialized tool SearchCal with ~ 2.5M star diameters available.

Documentation

A paper and
poster presented at SPIE 2014 Montreal are associated with the JSDC version 2.
The Readme associated with the catalogue is also worth reading.
